Modifying the $content_width variable in Genesis

By

WordPress looks for the $content_width variable when determining the width of oEmbed items. To define this variable, you would put this in the functions.php file:

if ( ! isset( $content_width ) )
	$content_width = 600;

However this is kind of limiting especially since we can have multiple layouts in Genesis. So the Genesis team has made it easy to define different $content_widths. For Genesis child themes, we would use this instead:

$content_width = apply_filters( 'content_width', 580, 480, 900 );

The 3 numbers correspond to the content width of the default, small and large layouts. The default layout refers to 2-column layouts; small refers to 3-column layouts and large refers to the full-width content layout.

You can combine this with the following method (borrowed from Twenty Twelve) to apply a different $content_width to different contexts and page templates.

function twentytwelve_content_width() {
	if ( is_page_template( 'page-templates/full-width.php' ) || is_attachment() || ! is_active_sidebar( 'sidebar-1' ) ) {
		global $content_width;
		$content_width = 960;
	}
}
add_action( 'template_redirect', 'twentytwelve_content_width' );

Remove Genesis layout settings for a Custom Post Type

By

If you’ve forced a layout for a custom post type, there’s no need to display the Layout Settings metabox in the edit screen. Here’s a code snippet that removes the layout options for a product custom post type.

/** Remove Genesis inpost layouts from 'product' post_type */
add_action( 'init', 'child_remove_post_type_support' );
function child_remove_post_type_support() {
	remove_post_type_support( 'product', 'genesis-layouts' );
}

Replace product with the custom post type you want this to work for.

Force a layout in a template

By

Here’s a code snippet you can use when you want to lock down a layout for a specific template. Just drop the following into a single-posttype.php, template-something.php, etc before the genesis() function:

add_filter( 'genesis_pre_get_option_site_layout', '__genesis_return_full_width_content' );

Note: __genesis_return_full_width_content is a helper function built into Genesis. See the end of this post on all available helper functions: Overriding Options and Meta.

Alternate method from Brad in the comments below which can go in functions.php:

/** Force full width layout */
add_filter( 'genesis_pre_get_option_site_layout', 'child_do_layout' );
function child_do_layout( $opt ) {
	if ( is_single() ) { // Modify the conditions to apply the layout to here
		$opt = 'full-width-content'; // You can change this to any Genesis layout
		return $opt;
	}
}

As a reminder, Genesis comes with 6 default layouts:

content-sidebar
sidebar-content
content-sidebar-sidebar
sidebar-sidebar-content
sidebar-content-sidebar
full-width-content

See Brian Gardner’s post on creating a landing page in Genesis for a practical example of how you would use this.
